ABSTRACT

High temperature and high pressure entrained flow coal gasification technology is the key technology of coal utilization, and the chemical and physical properties of coal and coke have an important impact on the thermal performance of coal gasification reaction. Based on the research and analysis of the physical and chemical processes of drying, hydrolysis, gasification and combustion in the process of coal gasification, this paper establishes the chemical equilibrium equation of gas composition by using the method of material balance and heat balance, calculates the indexes of coal gasification process, such as carbon conversion rate, cold gas efficiency, specific coal consumption, specific oxygen consumption, and probes into the operation pressure, specific energy consumption, specific energy consumption. The effects of operating temperature, oxygen coal ratio and steam coal ratio on gasification characteristics, such as coal gasification efficiency, coal gas yield and carbon conversion, provide theoretical guidance for the application of high temperature and high pressure coal gasification technology.
